The lithium zinc silicate glass exhibits two crystallization exotherms corresponding to the formation of Li 2 ZnSiO 4 and silica phases, respectively. The silica phases include tridymite and cristobalite. The influence of Ta 2 O 5 additions on the th

Chloride-containing radioactive wastes are generated during the pyrochemical reprocessing of Pu metal. Immobilization of these wastes in borosilicate glass or Synroc-type ceramics is not viable due to the very low solubility of chlorides in these hos

Immobilization of special categories of radioactive wastes containing both actinide and chloride species is of increasing interest. In the present contribution we report the results of investigations into the feasibility of immobilizing these wastes

A ternary sodium aluminophosphate glass, NaAlP, has been used as an encapsulating phase for a calcium phosphate ceramic employed as a host for halide-containing radioactive waste, the final wasteform being prepared by a pressureless consolidation rou

The crystallization kinetics of a lithium zinc silicate glass have been determined using isothermal and non-isothermal DSC and non-isothermal DTA. Values for the kinetic parameters for as-quenched and nucleated samples are reported and discussed. Par

Although small quantities of radioactive waste existed before nuclear weapons were built, their manufacture led to a dramatic increase in both the quantity of waste and its activity. These wastes arose from the entire manufacturing process starting w

The influence of alloying substitutions from the 3d, 4d and 5d transition series on the thermal-stabilities of Fe-, Ni- and Co-based metallic glasses containing 10 at.%Si and 12 at.%B glass formers has been systematically investigated. The changes ar

The relative glass-forming ability (GFA) of metallic alloys is considered in terms of a parameter ΔT ∗ = (T liq mix − T liq )/T liq mix , which represents the departure of the alloy liquids temperature, Tliq, from that of the simple rule of mixt
